See the original article here: Crystal Structure Discovered Almost 200 Years Ago May Revolutionize Solar Cells

Solar energy researchers at Oregon State University are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago. Not all materials with the structure, known as perovskites, are semiconductors. But perovskites based on a metal and a halogen are, and they hold tremendous potential as photovoltaic cells that could be much less expensive to make than the silicon-based cells that have owned the market since its inception in the 1950s. Enough potential, researchers say, to perhaps someday carve significantly into fossil fuels’ share of the energy […] Perovskite structure. Credit: John Labram, Oregon State University
